Abstract (en)
Provided is an LED lamp manufactured by an injection molding process, including a strip-shaped LED lamp, wherein the strip-shaped LED lamp includes a first strip-shaped conducting wire and a least one LED luminous body disposed on the strip-shaped conducting wire, and each of the LED luminous bodies includes a first chip and a second chip connected to the first chip via a second conducting wire; the LED lamp manufactured by the injection molding process further includes an injection molding body, and the first strip-shaped conducting wire penetrates into the injection molding body; the injection molding body is further formed, in an injection molding manner, with a fixing portion for fixing the LED lamp manufactured by the injection molding process in a hole to be penetrated; the first chip in each of the LED luminous bodies is an LED chip, and the second chip is used for controlling the power supply for the LED chip; and printed circuit boards and resistors are omitted in the LED luminous bodies. The structure of the LED lamp manufactured by the injection molding process and a potential process therefor in the present invention are simpler in comparison with those in the prior art, which is beneficial to the reduction of the fault rate, the increment of the production efficiency and the reduction of the production cost.
